Global mechanism of methane autoignition: Approach and algorithm

Abstract

An approach to constructing universal global mechanisms of methane autoignition is proposed. It is based on the requirement of obligatory reproduction of all the kinetic stages of the autoignition process and the types of their kinetics. It is shown that satisfying these requirements enables to construct global mechanisms of methane autoignition that are applicable in a wide range of initial conditions and adaptable to new problems. A global autoignition mechanism (10 species and reactions 9) is developed, as well as an extended global mechanism for describing plasma-induced methane autoignition (10 species, 10 reactions).
